Feat: show info on loaded instructions in tool metadata info

[webbugt]

Hello, love the plugin. I consider the scoped instructions the Copilot way far superior to the regular AGENTS.md, or other global instruction systems, especially in monorepo setups.

Tldr: Add additional info on which instructions were loaded:

read some typescript and test files so I can confirm tool output
→ Read . 
→ Read src 
→ Read src/index.ts 
↳ Loaded copilot-instructions.md (47 tokens)
↳ Loaded typescript.instructions.md (38 tokens)
↳ Loaded Total: 2 instructions active (85 tokens, <0.1% of context)
→ Read src/frontmatter.ts 
→ Read src/matcher.ts 
→ Read src/loader.ts 
→ Read src/frontmatter.test.ts 
↳ Loaded test.instructions.md (34 tokens)
↳ Loaded Total: 3 instructions active (119 tokens, <0.1% of context)
→ Read src/index.test.ts 

• updates plugin and dependencies to latest opencode-ai versions
• implements js-tiktoken for token estimate (should be 95% accurate)
• shows injected instructions after tool call (maybe move this before for Copilot-like experience)
• shows relative size of instructions to current model's context size (great for debugging overbloated instructions)

Pull request overview

This PR adds visibility into which instruction files are loaded by displaying them in tool metadata. When path-specific instructions are injected during file operations (read, edit, write), the plugin now populates the metadata.loaded array with the paths of loaded instruction files and a summary count.

Changes:

• Modified SessionState to track both instruction text and loaded file paths for each pending tool call
• Updated tool.execute.after hook to populate output.metadata.loaded with instruction file paths and a total count summary
• Upgraded @opencode-ai/plugin and @opencode-ai/sdk dependencies from 1.1.3 to 1.1.65

@ekroon Hello, any chance this get's merged/reviewed? :3
I have another improvement that I've made, tl:dr; an agent for optimizing instructions
